What Causes Condensation And Mold On Windows?condensation


When the temperature drops outside, its time for us to turn on the heat.


However, sometimes we wake up to condensation on our windows which can be more serious than you think. 


When the hot air inside your home rises and meets with a cold surface such as your windows, the water vapor cools down and turns back into water droplets. 


When water droplets form on your windows, this can create mold growth which may spread onto other surfaces.


Why is this dangerous?

In severe cases, this can cause widespread mold growth resulting in a heavily contaminated area. 


Mold is dangerous for your health and if it isn’t remediated properly…


can result in health issues. 


So you might be wondering….


How To 

Prevent Mold 

From Window Condensation


There are a few methods to prevent condensation on your windows during the winter.


The first two methods prevent condensation but the last one removes it before it has a chance to cause mold growth.


In combination, these three methods can help prevent condensation and mold growth on windows during the winter.


1. Increase the surface temperature of window glass and window frames


During the colder months when the temperature drops, the inside of our homes are warmed by heaters, and natural air currents that circulate inside the home. 


When the warmer air meets cold surfaces, the water vapor from the humidity cools and forms water droplets.

If windows are blocked by curtains and blinds, this allows for the space between them to become cooler, causing more condensation. 


Sometimes, allowing air to flow naturally (leaving blinds and curtains open) can reduce condensation. 


But how?


Using a small fan to increase warm airflow to windows can prevent increased condensation forming on windows.

Increase room temperature which can help minimize condensation and mold buildup. However,

This isn’t very energy efficient and can add to your heating bill. 



2. Reduce humidity in the room


Another method to prevent condensation and mold buildup on windows is by reducing the amount of humidity in the air. dehum


The easiest way to reduce humidity is with a dehumidifier.


These machines draw warm moist air from the environment, cool it to condense the moisture, then warm it back up and disperse it into the room. 


What does this do?


This can help remove excess humidity and stop condensation and mold from forming on your windows.


Understandably restoration companies have more efficient and expensive equipment, but you can find a small humidifier at your local hardware store that will also do the trick.


3. Cleaning up condensation and mold

This last method revolves around minimizing mold growth by cleaning condensation every morning.


This prevents mold growth by removing a comfortable environment for it to grow in.


If you close your blinds or curtains at night, open them in the morning to allow for airflow.

This can increases circulation and speeds up the evaporation time. 


For more serious mold problems, contact one of your local restoration companies to help you clean it.
